In a large soup pot, heat olive oil over medium-high heat.
Add ground chicken and cook until no longer pink, breaking up the ground chicken as it cooks into small pieces.
Add onion and bell pepper, and cook until beginning to soften, about 5-7 minutes.
Add garlic, chili powder, cumin, cayenne pepper, and salt, stir well, and cook another minute.
Add beans, pumpkin, diced tomatoes, and corn, and stir well.
Bring to a simmer, then reduce heat to low and let simmer for about 20 minutes to let flavors develop.
Serve topped with green onion, cheese, and sour cream/Greek yogurt and along with cornbread or tortilla chips
Enjoy!
